The fundamentals of indoor cannabis cultivation
How long does cannabis take to grow?
From the time you start (with seeds or clones) to the time you harvest, it will take roughly 4 months. With more vegetative time, growth times can be extended, resulting in larger plants and yields. You’ll also need to account for curing time after the harvest to ensure high-quality buds. Learn more about how long cannabis takes to grow.
Selecting a Strain
What does it cost to grow cannabis indoors?
Depending on the size of your grow space and the amount of equipment you want to use, you’ll require different amounts of money. In terms of lighting, ventilation, and other equipment requirements, the larger the growth, the more complicated the setup might be.
What tools are required to cultivate cannabis?
The equipment you’ll need for your room will depend on the results you want to achieve. View a list of everything you’ll need for growing tents or growing rooms. A light setup (with bulb, reflector hood, and ballast), a light timer, light hanger cables, a small fan or two for air circulation, growing media (soil/soilless mix/coco/or a hydro setup), and a ventilation system with an inline fan are all required for a small tent and grow room setups.
Air-cooled lighting hoods are beneficial for 600 Watt and bigger MH/HPS setups. Carbon filters are required to remove odors from expelled air. To lessen noise and vibration, utilize a larger fan at a slower speed with a fan controller.
Growers that use 1000 Watt illumination must contend with heat, which frequently necessitates the use of air conditioning and carbon dioxide systems. To monitor environmental conditions in the grow chamber, you’ll also need a thermometer with a hygrometer.
Cannabis Growth Stages
- Seeds germinating and clones rooted:
Because they don’t have access to clones, first-time growers frequently use seeds. If you’re going to grow from seed, it’s better to get some good seed stock than to choose a few random seeds from a bag of cannabis and hope for the best. Cannabis plants can only develop to the potential of their DNA, and growing a great THC-laden strain requires the same amount of effort as growing any random trash seed phenotype that remained after you finished your last bag. You’ll be rewarded with great plants if you start with great seeds from a trusted source.
Because standard seed packs can contain both males and females, plan on germinating at least twice as many seeds as the total number of plants you desire, as the males will need to be removed to prevent the females from producing seeds. Because not all rooted seeds will grow as vigorously as others, having a few extras will allow you to weed out the scraggly growers.
Feminized seeds eliminate undesired males, but because they tend to become hermaphrodites, they aren’t good for gardeners wishing to make clones for future crops. Learn how to grow seeds in coco coir, soilless mixtures, and Rockwool cubes.
You can ensure a fresh generation of female plant stock identical to the parent if you have access to clones. Keep a mother plant in a vegetative state to ensure a consistent supply of clones for growers that want to ensure a steady supply of the next generation.
Planning for a constant harvest allows you to have a well-timed batch of plants in vegetation ready to enter flowering as soon as the previous batch is harvested, allowing you to harvest a new crop every 8 weeks.
- cannabis in its vegetative state:
Your plant begins the vegetative stage after you’ve rooted a seed or clone. The vegetative stage, which usually lasts 2-4 weeks but can last up to several months depending on the desired size, allows the root structure to grow as well as the leaf growth that pushes the plant through the rigors of flowering.
Plants in the vegetative stage normally receive 18 hours of light, however, some gardeners give them a full 24 hours. Plants can be trained to enhance their growth structure so that more of their buds are exposed to light, which improves quality.
- cannabis is now in its flowering stage:
The plant enters the flowering cycle when the lights are switched to 12 hours on and 12 hours off. Depending on the strain, flowering can continue up to 8 weeks, with Sativa strains often lasting longer than Indica strains.
For healthy, robust blooms with optimal potency, flowering cannabis plants require 12 hours of uninterrupted darkness. Even a modest amount of light can confuse plants, resulting in complications such as hermaphrodite plants, which generate seeds in response to environmental or other pressures. This has a negative effect on potency and should be avoided. To cultivate high-quality buds, you’ll need to know how to grow cannabis without seeds.
Harvesting at the right time will optimize potency and production. To ensure optimal efficacy, it’s critical to harvest plants at the proper time. Plants will not have grown all of their THC if they are harvested too soon. If you wait too long, THC will degrade into CBN, altering the high’s effect. Find out how to tell when it’s time to harvest cannabis.
Plants must be clipped and properly dried after harvesting, which normally takes 3-7 days. Buds must be cured for at least two weeks after trying to improve the taste, smell, and smoothness of the smoke as the plant chemicals break down.
It’s critical to cure your cannabis properly if you want your buds to reach their full potential in terms of appearance, flavor, fragrance, and quality.
